In this equilibrium worksheet, students perform a computer simulation on vapor pressure of water at different temperatures to answer 11 problem solving and short answer questions about the topic.

In this scientific method worksheet, students read over the basic steps of the scientific method and then apply those steps to a specific example. This worksheet has 8 short answer questions.

For this density worksheet, students investigate what will happen when various liquids with different densities are put into the same container. They hypothesis and make observations. Students answer 4 questions about their investigation...

Learners explore how fish are able to move easily from one depth to another in water.  In this fish lesson students create their own balloon fish. 

In this rate of chemical reactions worksheet, learners experiment with different concentrations and volumes of hydrochloric acid mixed with magnesium to explore the rate of chemical reactions. They measure the rates of the reactions and...

In this density activity, students use the mass of aluminum and copper at different volumes to create a graph in order to calculate the density of these metals. This activity has 1 graph, 2 short answer, and 5 word problems.

Students find the density of two substances. In this density lesson plan, students determine the density of water and ethyl alcohol and compare their densities. They enter their data into the computer to produce a class compiled graph....

Students investigate density and salinity of water. In this density and salinity lesson plan, students find the density of objects and liquids and show the relationship between the salinity and density of water. Students add salt to...

In this salt front of the Hudson River worksheet, 7th graders first read an excerpt about the lower portion of the Hudson River that is an estuary. Then they use a colored pencil to plot salinity data from the table shown on a graph,...

Learners identify and describe various organisms living in a pond water environment. They describe the characteristics of living things. Students compare and contrast organisms created by asexual reproduction and sexual reproduction....

Students use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

In this density worksheet, high schoolers review this property of matter and the mathematical equations for density, mass, and volume. The worksheet has 10 fill in the blank statements and 3 word problems.

Students arrange containers by their capacity. For this volume lesson, students place containers in order by increasing capacity. Students discuss how the tallest container doesn't necessarily hold the largest amount.

Learners identify the physical and chemical properties of matter. They review the types of matter. Students list the four states of matter (Solid, Liquid, Gas and Plasma). They recognize and describe the different types of matter.

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

Geometric volume calculations are brought into the real world in a quick set of application problems. Learners are asked to help a patient figure out how to drink a prescribed amount of water both at work and at home. This activity...

Cell size is limited by the surface area to volume ratio, but why is this true? Scholars measure the surface area and volume of cubes before placing them into liquid. After a set amount of time, they measure the uptake by diffusion for...

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

Temperature rises and land disappears! Through a lab exploration, learners understand the effect of temperature increase on water similar to the effect of global warming on our oceans. As they heat the water in a flask, they measure the...

In this acids, bases and salts activity, high schoolers solve five problems in order to determine the molarity of solutions or the volume of substances to be added to make molar solutions. They also solve five dilution problems about acids.

Students investigate why cells divide. In this cell size lesson plan, students observe how far a solution travels into 3 different size model cells of agar. They answer questions about the most effect movement of "nutrients" into the...

High schoolers investigate inhalation and exhalation of the respiratory system. They construct a model of the respiratory system using balloons, straws, cups, and rubber bands. Then, they observe inhalation and exhalation and measure the...

Young scholars examine why diffusion and osmosis happen in an egg cell.  In this diffusion lesson plan students demonstrate a semi permeable membrane.

As your young learners develop into cooking enthusiasts, ensure their success in creating their next culinary masterpiece by preparing them to read and understand basic recipe terminology.
